1.2SYSTEM DESCRIPTION
A.Hydro-Prufe® is a un-reinforced 80 mil PVC Thermoplastic Sheet Membrane:
The Hydro-Prufe® systemis designed to provide the ultimate protection whenused in compliance with the manufacturer’s specifications. The PVC membranecomes in 80 mil thickness. Hydro-Prufe® uses the induction method ofweldingthe liner to the substrates theyare protecting. This Electro-Bondingsystemadheres the PVC liner to the substrate byheatingthe fasteningplates behind thePVC liner which results in a permanent bond fromthe PVC Thermoplastic liner tothe plates.
